Optimize Parameters for Keras Model?

hi @LuatNV sorry no one has chimed in here. Is this still a problem?

Hi LuatNV: Though I've never done this with the Keras operator, in theory you should be able to use one of the Various "Optimize Parameters" operators - such as "Optimize Parameters Grid"  - which is ussualy a good place to start.  This operator provides a dialog that lets you specify which parameter(s) within what operator(s) you want to optimize and provide starting and ending parameter values to test.  This operator outputs information that gives you the optimal settings for the parameters you chose to optimize.  Bear in mind that depending on how many parameters you want to  optimize, and the spread of starting and ending values, and the number of data rows, your process may require quite some time to run.  A way to get around very long run times is to use a sample of your data on the assumption that a sample of between 25% - 50% is in the majority cases representative of the range of values you would see in your complete data set.  Hope this helps and best wishes, Michael Martin
